Control in console input?

"Exit program?(Y/N): " does not really do what the user expects ;-)

"Exit program?(Y/N): " does not really do what the user expects ;-)

Yes,yes, that's right, is just the end of the program, just a mark to distinguish the others parts: the loop back to the beginning, because of the input error, from the correct way. 
Thanks for trying it jj!  :t
Btw: Also it should say maximum not maximun, right?

Right ;)

In the meantime, I have added the option to limit the input to n characters to the Input$() macro, see here. Thanks for inspiring me, this is a useful feature :t
